DJs use two turntables for a few reasons. Firstly, it allows them to mix between two different tracks seamlessly, maintaining a continuous beat for the audience. Secondly, having two turntables provides more options for creativity, such as beat juggling and scratching, which involve playing and manipulating sounds from both turntables simultaneously. Finally, in case one turntable fails or malfunctions during a performance, having a second one ensures that the music can keep playing without interruption.
